Abstract: Codebook designs are disclosed for full-dimensional multiple-input-multiple output (FD-MIMO) wireless cellular systems. The FD-MIMO cookbooks employ channel state information reference signals (CSI-RS). The codebook designs are used in beamforming CSI-RSs by the enhanced nodeB (eNB), where the CSI-RS is sent to the user equipment (UE), enabling the UE to perform channel estimation. The codebooks support beam selection, co-phasing between polarizations, and beam combining.

Abstract: User equipment (UE), an enhanced NodeB (eNB) and method of improving positioning accuracy and enabling vertical domain positioning of the UE are generally described. The UE may receive a prsInfo control signal having at least one PRS configuration and subsequently a plurality of Reference Signals (RSs). The RSs may have a first Positioning Reference Signal (PRS) pattern in a first set of PRS subframes and a second PRS pattern in a second set of PRS subframes received prior to a subsequent first set of PRS subframes. The RSs may have a vertical positioning RS and a lateral positioning RS. The UE may measure PRS resource elements (REs), each having a PRS, in the first and second PRS pattern. The UE may transmit a measurement of the PRS in the first and second PRS pattern. The patterns may enable horizontal and vertical positioning to be determined.

Abstract: Described is an apparatus of an Evolved Node-B (eNB) comprising a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to generate a reference signal transmission for an eNB Transmitting (Tx) beam corresponding with at least a first eNB antenna port having a first polarization and a second eNB antenna port having a second polarization. The second circuitry may be operable to process one or more reporting transmissions carrying at least one of a first signal reception indication for a first UE antenna port and a second signal reception indication for a second UE antenna port. The third circuitry may be operable to determine a transmission hypothesis based upon the one or more reporting transmissions.

Abstract: Disclosed herein are apparatuses, systems, and methods for reference signal design for initial acquisition, by receiving a first primary synchronization signal (PSS) and a first secondary synchronization signal (SSS) from a first transmit (Tx) beam, in first contiguous orthogonal frequency division multiplexing (OFDM) symbols of a downlink subframe. A UE can receive at least a second PSS and a second SSS from a second Tx beam in contiguous OFDM symbols of the downlink subframe. A UE can then detect beamforming reference signals (BRSs) corresponding to the first Tx beam and the second Tx beam, based on identification of physical cell ID information and timing information processed from the first PSS, the second PSS, the first SSS, and the second SSS. The UE can select the first Tx beam or the second Tx beam that was received with the highest power, based on the BRSs. Other embodiments are described.

Abstract: Technology for a user equipment (UE) operable to decode a resource mapping pattern of a phase tracking reference signal (PT-RS) received from a base station in a wireless network is disclosed. The UE can decode control signaling received in a downlink from the base station. The control signaling can indicate a resource mapping pattern for a PT-RS. The UE can identify the resource mapping pattern for the PT-RS based on the control signaling received from the base station. The UE can encode one or more PT-RS for transmission to the base station in an uplink in accordance with the resource mapping pattern for the PT-RS.

Abstract: Embodiments described herein include devices, methods, and instructions for managing beam interpolation in massive multiple-input multiple-output (MIMO) communications. In one example embodiment, an evolved node B is configured to transmit to a UE using massive MIMO by transmitting multiple beamformed reference signals on multiple transmission beams each associated with a different plurality of antennas. The eNB receives beam interpolation information back from the UE, and then generates a data transmission that is sent to the UE using an interpolated transmission beam from a first and second transmission beam.

Abstract: Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), and methods for communication of uplink messages are generally described herein. The UE may receive, from an eNB, one or more downlink control messages that may indicate an allocation of PUCCH channel resources. The UE may transmit an uplink control message in at least a portion of the allocated PUCCH channel resources. When the PUCCH channel resources are allocated according to an edge configuration, the PUCCH channel resources may be restricted to a lower edge portion and an upper edge portion of the network channel resources. When the PUCCH channel resources are allocated according to a distributed configuration, the PUCCH channel resources may include one or more middle portions of the network channel resources. The middle portions may be exclusive to the lower edge and upper edge portions.
